Belt Maintenance

Adjusting the Alternator
Belt
Service Interval: After the first 8 hours
Ensure that the belt is properly tensioned to ensure
proper operation of the machine and prevent
unnecessary wear.
1. Park the machine on a level surface, shut off the
engine, engage the parking brake, remove the
key, and wait for all moving parts to stop.
2. Apply moderate thumb pressure to the belt
between the pulleys (10 kg or 22 lb). The belt
should deflect 7 to 9 mm (0.28 to 0.35 inch). If
not, complete the following procedure to adjust
the belt tension:

C. Using a lever placed between the alternator
and the engine block, pull the alternator out
to obtain the correct belt tension and tighten
the bolts.
Hydraulic System
Maintenance

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Servicing the Hydraulic
Fluid
Important:
Regardless of the hydraulic fluid type
used, any machine used for mowing fairways,
verticutting, or used during ambient temperatures
above 29°C (85°F) should have the Oil Cooler Kit
(Part No. 117-9314) installed.
Hydraulic Fluid Specifications
g014755
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
5-gallon pails or 55-gallon drums. See the Parts Catalog or
your authorized Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. The
use of synthetic fluid is not recommended. Consult
with your lubricant distributor to identify a satisfactory
product.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
